Question 1

According to the quantity theory of money, what is the primary cause of long-run inflation?

Accepted Answer

Excessive growth in the money supply

Question 2

If the price level $$P$$ increases from $$2 to$$ $$4$$, what happens to the value of money $$1/P$$?

Accepted Answer

$$1/P$$ decreases from $$0.5 to$$ $$0.25$$

Question 3

Suppose the Federal Reserve increases the money supply. According to the money supply-demand diagram, what is the immediate effect on the price level $$P$$ and the value of money $$1/P$$?

Accepted Answer

Price level $$P$$ rises, value of money $$1/P$$ falls

Question 4

Given the velocity of money formula $$V = \frac{P 	imes Y}{M}$$, if $$P = 5$$, $$Y = 800$$, and $$M = 2000$$, what is the velocity of money?

Accepted Answer

$$V = 2$$

Question 5

If the money supply $$M$$ increases by 5% and velocity $$V is $$constant, but real GDP $$Y$$ does not change, by what percentage does the price level $$P$$ change according to the quantity equation $$M 	imes V = P 	imes Y$$?

Accepted Answer

P increases by 5%

Question 6

Suppose in 2024, the money supply $$M = 2000$$, price level $$P = 5$$, and real GDP $$Y = 800. In 2025$$, the Fed increases $$M by 5$$% to $$2100$$, and $$Y$$ remains at $$800. $$What is the new price level $$P in 2025$$?

Accepted Answer

$$P = 5.25$$

Question 7

If the government prints money to pay for its spending, what is the economic term for the resulting increase in prices and reduction in the value of money?

Accepted Answer

Inflation tax

Question 8

Which of the following best describes the Fisher effect?

Accepted Answer

The nominal interest rate adjusts one-for-one with changes in the inflation rate

Question 9

If the nominal interest rate is 8% and the inflation rate is 3%, what is the real interest rate according to the Fisher equation?

Accepted Answer

$$5\%$$

Question 10

Which of the following is NOT a cost of inflation described in the study materials?

Accepted Answer

Increase in real incomes

Question 11

During periods of unexpected high inflation, which group benefits most according to the study materials?

Accepted Answer

Debtors

Question 12

If inflation is 10% and the nominal interest rate is 20%, with a tax rate of 25%, what is the after-tax real interest rate?

Accepted Answer

$$5\%$$

Question 13

Which of the following statements about hyperinflation is correct?

Accepted Answer

Hyperinflation is always caused by excessive growth in the money supply

Question 14

If the velocity of money $$V is $$constant and real GDP $$Y$$ increases by 3% while the money supply $$M$$ increases by 5%, what is the approximate inflation rate?

Accepted Answer

2%

Question 15

Which of the following best explains why inflation can distort taxes?

Accepted Answer

Taxes are based on nominal income, which rises faster than real income during inflation

Question 16

What is the main reason that 'shoeleather costs' arise during periods of high inflation?

Accepted Answer

People make more frequent bank withdrawals to avoid holding depreciating money

Question 17

According to the quantity theory of money, if $$M 	imes V = P 	imes Y$$ and $$V is $$stable, what happens if $$M$$ doubles and $$Y$$ remains constant?

Accepted Answer

$$P$$ doubles

Question 18

Which of the following is an example of a 'menu cost'?

Accepted Answer

Printing new price lists and catalogs

Question 19

In the long run, what determines real incomes according to the study materials?

Accepted Answer

Real variables such as technology and resources

Question 20

If the price level $$P is$$ $$10$$ and the value of money $$1/P is$$ $$0.1$$, what does this mean in terms of purchasing power?

Accepted Answer

Each dollar buys 0.1 units of goods
